A's 4, Mariners 3

SEATTLE — Josh Donaldson, Daric Barton and Brandon Moss hit solo homers, and Jarrod Parker pitched into the seventh as the Athletics held on to end a season-long five-game losing streak. Parker didn't give up a hit until Kelly Shoppach's two-out, two-run homer in the fifth. Grant Balfour worked around a two-on jam in the ninth for his sixth save in six chances.
